Personally I adore that symphony, and also found many of his other works absorbing: Amen, Beatus Vir, and Totus Tuus are all music of sweeping power and beauty; late works like Kleines Requiem for a Polka and the three String Quartets (No.1, 2, 3) are also fresh and distinctive.
This playlist features all Górecki's recorded works available; sorted in chronological order. From op. 1 (1955) to op. 75 (1999), plus one unnumbered piece Three Dances in Old Style (1963). For Symphony No.3 I used the Zinman recording. The composer's own favorite: Wlodzimierz Kamirski conducting the Radio Symphony Orchestra Berlin with soprano Stefania Woytowicz, is hard to find in the west and not on Spotify, though another recording featuring the soprano, and the conductor who premiered the symphony with her, is on Spotify US.
